Matrix phased array probes

3D beam control

Principle

3D beam control
- Focusing depth is electronically selected
- 3D beam steering is feasible thanks to 2D active elements pattern

More details about phased array principle here >>

Typical use in immersion, direct contact or contact with a wedge
Typical use with pulse echo technique
Possible use with Time Reversal Mirror technique (M. Fink)

Applications

Inspection of complex geometry pieces with small access area
Inspection of non homogeneous materials (with TRM technique)

Advantages

Feasibility of new inspections
Performance improvements

Typical configurations
